-BUNG.

SPECIFICATION forming part of Letters Patent No. 573,624, dated December 22, 1896. Application filed July 28,1896. Serial No. 600,772. (No model.)

T all whom it may concern.-

Be it known that I, HENRY ROSENTHAL, a citizen of the United States, and a resident of the city, county, and State of New York, have invented a new and useful Improvement in Bungs, of which the following is a specification.

This invention relates to bun gs and closures for barrels, casks, or other vessels.

One of the objects of the invention is to provide a closure adapted to be driven inside the cask or other vessel which it closes and so arranged as to separate into sections whereby the removal of the bung or closure from within the cask or vessel may be facilitated. In carryin g out this object the closure may be made solid, with one or more lines of separation, so that the entire closure may be driven inside the cask or vessel and may separate into two or more sections, and these sections may be made separate and united together to form the solid closure by suitable means, or the closure may be made in one piece and provided with one or more slits which will enable the closure to separate into sections when driven inside the cask or other vessel. This object may also be carried out by providing a tubular bung with a detachable closure, the closure being adapted alone to be driven inside the cask or vessel and to separate into sections. The closure for the tubular portion in this case has lines of separation and may be made either integral with or separate from the tubular portion, and when made separate from the tubular portion such closure may itself be made in one piece or in separate sections fitted closely together and united with the tubular portion by suitable means.

Another object of the invention is to provide a bung made in one piece having a tubular body portion and a closure therefor integral with the body portion, but detachable therefrom. In carrying out this object the bung is generally cut from one piece of wood, and around the periphery of the bung a line or slit of separation is made for the easy detachment of the closure, and the closure is also arranged to separate into sections when driven inside the cask or vessel.

The invention consists of the construction hereinafter set forth.

In the drawings showing various embodiments of my invention and forming part of this specification, and in which like letters of reference designate similar parts, Figure 1 is a side elevation, partly in section, showing a tubular bung having a detachable sectional closure all made in one piece. Fig. 2 is a similar view, but showing a tubular bung having a separate detachable sectional clo sure suitably united with the tubular body portion and made in one piece. Fig. 3 is a bottom plan view of the bung shown in Fig. 2. Fig. 4 is a side elevation, partly in section, showing a tubular bung in operative position in the wall of a cask or other vessel, the sectional closure being made separate from the tubular portion. Fig. 5 is a bottom plan View of the closure shown in Fig. 4, with the sections fitted together. Fig. 6 is a view showing the separate sections of the closure separated. Fig. 7 is a side elevation of a tubular bung having a separate sectional closure made in one piece and suitably secured to the tubular portion, the bung being in operative position in the wall of a cask or other vessel.

Referring now more particularly to the details of the invention, especially as shown in the drawings, A designates a bung comprising a tubular portion a and a closure for the tubular portion. The closure 1), Fig. 1, and closure 6, Figs. 2 to 7, inclusive, have one or more lines or slits d, which divide them into two or more sections. These lines may run in any direction, and in some cases may extend only partly through the closure, so as to leave the closure formed in one integral piece, but divided up into sections, as shown in Figs. 2, 3, and 7, or may extend all the way through, so as to divide the closure up into two or more separate sections, all arranged so as to fit closely together, as shown in Figs. 4, 5, and 6.

In some cases the bung is made in one piece, as shown. The closure 6 is a separate piece from the tubular body portion a and is secured thereto by suitable means, such as glue or pins f (shown in Fig. 4) or otherwise. The closure 1), Fig. 1, is divided up into sections by the lines d, but the lines do not extend all the way through the closure, so that the closure is in one piece. This closure 1) is also integral with the tubular portion a, the bung being formed in one piece. A line of separation 0 runs around the periphery of the closure, so as to leave it connected with the portion a by a thin web 0. p

In practice the bunghole of the cask or other vessel is generally provided with a permanent metallic tapering bushing B, into which the bung A is driven to close the hole.

The body portion Ct is slightly tapering to' correspond with the bore of the bushing, but in some cases the closure for the body portion is cylindrical in shape, that is, it has no taper. This form of closure is generally preferred, especially when the closure is separate from the body portion a, and is shown in Figs. 2 and 7. The bung shown in Fig. 7 is the same form as that shown in Fig. 2, that is, its closure is separate from the body portion a and the lines of separation are made by slits or saw-cuts which do not go all the way through the closure. hen this bung is driven into the bushing, the sections of the closure are tightly compressed together at the bottom, as clearly shown in Fig. '7.

Vhen it is desired to tap the cask or other vessel closed by the bung having the sectional closure described, the vent or faucet is inserted in the tubular portion a of the bung and driven against the closure by a sharp blow. The closure is thus detached from the body portion a and at the same time separates into sections. The tubular portion a forms a tight-fitting bushing for the vent or faucet and effectually prevents leakage. After the cask or other vessel is emptied of its contents the sections of the closure can be easily removed from the vent or bunghole during the process of washing.

lVhile I have described and illustrated in the drawings the forms of bung embodying myinvention in ways now best known to me, it will be understood that certain changes in form and arrangement may be employed without departing from my invention.

lVhat I claim as new, and desire to secure by Letters Patent, is

1. A bunghole-closure adapted to be driven into the cask or vessel which it closes and having one or more lines of separation whereby the closure when driven inside the cask or,

4. A bung comprising a tapering tubular body portion and a separate cylindrical closure arranged to separate into sections, substantially as set forth.

5. A bung comprising a tubular body portion and a separate sectional closure therefor and means for securing the parts together, substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
